plants looking bad..

I posted this in the sick plant forum too figured someone would have an answer in one of these two places....

So, a few days ago, my plants started getting burnt on the tips of the leaves, I didn't think much of it, but it has been getting worse and worse.

I have been using nutrients very sparingly (stock AG nutrient tabs in half tab doses).

My pH is around 6.0

Have been using nothing but pH adjusted Ozarka spring water.

I flushed my res and put new water in a few days ago, and they haven't really started looking any better.

Does this mean they NEED nutes? or is this really bad nute burn?

I popped a half of a tab into my res, and I got a red blinking "ADD NUTRIENT" and "CHANGE WATER" light, so I freaked out and flushed my res asap and put a lower concentration of nutes in.

Could it be that my CFL is too close? its about 3-4" inches away from the plant.

I have been trying to ride this out like previous problems, but it just looks like its getting worse.

My roots look nice and healthy though.

Also, my plants were planted 1/28 and 1/31 so they are roughly 2.5 weeks old.




Any help would be greatly appreciated.

whats your water temp? also whats the box temp or the temp next to the AG? Did you put the AG Nutes in when u first started? I am not down with those nutes i went out and bought some pure blend to add in at week 2

Box temp ranges from 70-80

Res is around 75-85.

These plants had not seen anything but water for the first 2 weeks.

I just ordered some feminized seeds from drchronic, just in case these guys don't pull through.

how do the roots look? i also don't think much of the ag nutes especially if they've been sweating in the box.

really?

all of my nute bags have some kind of watery shit in them

does that mean all these nutes are garbage?

personally i would bin the ag nutes then, if they have sweated. the boxes my ag holders and sponges came in are all discoloured. pic attached. are your roots nice and white?

Oh, yea they didn't sweat through the box, I thought I spilled water or some shit on them at first when I had the master gardener kit on my sink counter, and all the bags had a little bit of water.

My roots aren't really that white anymore.

Damn im not too sure, isnt there supposed to be a certain PH for younger seedlings?, maybe 6 is a lil too high, the light blinks after a week or so, its kinda like a timer, you press reset and it go's away

Yea I have never had that light go off before, and it happened right after I put the nute tab in, was kind of weird I thought it was related.


They have been sitting at like 6.5 up until a few days ago.

I have no clue as to what the problem is it could be handful of things..

Well im guessing the PH is too high, im pretty sure 6 is too high, cause from what i've seen, people keep it at a steady 5.8 to 6 during the older stages of there lives, but i could be wrong, hope this helped haha

yeah sicc is right, the blinking lights mean shit. they do just work via a timer. the ag doesn't detect anything.

i haven't had to worry about ph to much just so long as its within the accepted range.

those roots don't look healthy but they don't look unrecoverable. best advice i could give would be clean out the rez, rinse the roots (make sure water not to cold or warm). can't remember if you have an airstone but if you do clean it thoroughly with some h2o2 or pythoff or some bleach. make sure to rinse well before using it. just use plain water to refill, ph'd to 5.5ish if you can. you can probably unplug the ag and just use a power cord and timer to power the light hood, if all your babies have roots that reach the water.

Yea thats probably what it is, I checked the pH of my res and it was like 6.5!!!

I added some pH down in there (3 drops) should put it at 6.2 in a few hours, then ill put another 2 in there to hopefully get it to 6.0

I don't really want to mess with anything below that because I cant read below 6.0 on my test kit.

Yea I have a separate timer for my AG hood and other lights already.

I have a 10 inch airstone directly below my roots.

My roots are really long..

I dont have any hydrogen peroxide on hand, and I'm sick at shit right now so I can't go to the store.

would soaking my airstone in some really hot almost boiling water work?

i haven't tried it personally but boiling water with a bit of toilet bleach wouldn't hurt. when you change out your rez check for any crap in the water like brown floaty bits. that would be algea. if you have any then see if your airstone has any growing on it. if you see nothing in the rez or on the airstone just give the rez a scrub and refill with ph'd water and no nutes. then give it a few days and see how you go.

Yea theres nothing in my res but clean water and 1/3 of a nute tab.

I cleaned it out yesterday.
